Brehm #5 Flashcards
Steps in the evolution of a LOB (4)
- emergence
- control
- breakdown
- reorganization
Description of the emergence phase of the LOB evolution cycle
as new LOB arises, data is thin, demand grows quickly, and pricing is erratic (price wars set in with new competition)
eventual solvency crisis forces price correction where weak competitors exit, followed by a period of profitability before the cycle “restarts”
Description of the control phase of the LOB evolution cycle
stabilization obtained through collective coercive control where rating bureaus and DOIs regulate price changes and restrict entry
Description of the breakdown phase of the LOB evolution cycle
control regime breaks down as technology and societal changes bring in new competitors (not under control) who take business away
Description of the reorganization phase of the LOB evolution cycle
a new version of the LOB emerges and returns to emergence phase conditions
Phases of LOB evolution driven by competition (3) vs. statistical data lags (2)
competition - emergence, breakdown, and reorganization
data lags - control and breakdown
Underlying themes of the UW cycle (3)
- time lags b/w compilation of historical data and implementation of new rates»_space; poor extrapolation of rate need
- competition and relatively poor quality of forecasting abilities from inexperienced firms pushes the market towards lower prices
- impact of capital flows on supply and demand
Dependent (2) and independent (5) variable examples in an UW cycle model
dependent: LR or CR
independent:
1. historical values of dependent variable/components
2. financial variables
3. regulatory/rating variables
4. econometric variables (ex: inflation, unemployment, GNP)
5. financial market variables (ex: interest rates, stock market returns)
Dimensions (3) of modeling styles and ranking of approaches
- data quantity, variety, and complexity: soft > behavioral > technical
- recognition of human factors: soft > behavioral > technical
- mathematical formalism and rigor: technical > behavioral > soft
Types of approaches to modeling the UW cycle (3)
- soft
- behavioral/econometric
- technical
Examples of soft approaches to modeling the UW cycle (3)
- scenarios
- Delphi method
- competitor analysis
Examples of technical approaches to modeling the UW cycle (2)
- autoregressive time series analysis
2. general factor model
Key components of behavioral/econometric approaches to modeling the UW cycle (2)
- supply and demand curves
2. available capital
Supply curve and impact of post-shock and competitive limits
in order to bring more quantity (supply) to market, must increase price (so moves up and right)
post-shock: under restricted capital, must increase price to maintain quantity
competitive limit: under pressure of new entrants and technological advancements, must reduce price to maintain quantity
Demand curve and impact of post-shock and capital-rich environments
in order to sell more, firms must reduce price (so moves down and right)
post-shock: under restricted capital (lower quality capital), lower quantity demanded at the same price
capital-rich: with higher quality capital (= lower probability of default), more quantity demanded at the same price
